Abstract (en)
An electronic typewriter has an electronic control circuit (21) housed with the usual typing mechanism in a casing (13), and can be provided with a display module (22) for displaying text and/or machine functions. The display module is removably fixed (26) to the casing. An electronic unit (77) for controlling the display module is removably fitted in the casing and is connected to the control circuit (21) and the display module (22) by connectors (91, 92; 97, 98). A basic typewriter without a display module can be constructed with a cover (24) instead of the display module. The two types of typewriter can be produced on largely the same production line, and the basic typewriter can be simply upgraded with a display module in the field. <IMAGE>
